A very humid start to Tuesday, with a feel-like temp already over 30C despite the cloud. Here’s the dew point for 7am this morning (dew point is the temp at which dew would form as the air reaches 100% humidity – so the higher the total the wetter the air – in these charts the redder the colour the more humidity – dew point in the 20s close to the coast):
Going to feel hot and sticky today, with a decent chance of a shower or storm through the day. There were actually a decent number of storms overnight – check out this map of lightning strikes and you can see how much activity there was to our north yesterday (orange) and overnight (red):
Coming up we’ve got a strong westerly blast tomorrow. The down side? The temps will be even higher…but the upside – away from the coastal strip the humidity levels should be much lower. Here’s the 1pm forecast dewpoint for Wednesday:
You can see how the higher humidity levels are kept right on the coastal strip. Going to be HOT though – here’s the forecast temps for 1pm:
Those westerly winds however will bring a day of Very High to Severe fire danger across much of eastern NSW. Here’s the preliminary forecast for tomorrow – shaping up to be a bad fire day:
A little cooler for Thursday, though not the real cool change we’d love to see. Looking further ahead there are signs of another heatwave in the 7 to 14 day period…

Some images to tell a story…With more cloud cover it was cooler today:
Looking much warmer for tomorrow (Tuesday):
Wednesday is looking really hot:
The big difference between today and Wednesday is the dew point – how humid it is. Close to the coast a sea breeze will likely keep humidity levels up, but you won’t need to go far inland, likely only to the valleys, perhaps Dorrigo, to see the westerly winds push through and lower dew points dramatically. Compare the two images below – dew point for today (left) and for Wednesday (right):
Combine the high temperatures, westerly winds and low humidity levels and we will likely see raised fire danger levels through the day. What we need is some rain…image below shows total forecast between now and Wednesday:
Not much, though any rain we do see will likely come from storms. Focus on the hills once again, though a chance tomorrow that we will see more in the way of showers and storms make it closer to the coast. Fingers crossed!
The good news? Thursday is looking much cooler 🙂
Getting Hot, Staying Hot……at least until next Thursday. Forecast 1pm temps for Sunday getting up there:
Monday – not much change…
Looking similar through until Wednesday. In the words of the BoM: “Severe to extreme heatwave conditions are forecast to develop over central and southeastern Queensland. The low intensity heatwave conditions shifts further north extending from the interior of WA, through central Australia, across northern NSW and also covering most of Queensland.”
Looks like a cool down will move through mid-week, cooling it down for Thursday:
No big rains likely any time soon, though some showers and storms are possible at times. Likely going to see fire danger levels potentially rising again as we dry out once more…Nothing too significant weather fire wise in the immediate outlook, which is good news for us.
